1. This parameter is given as application information and is not tested during production.
2. The oscillator drift is related to the picture carrier frequency, with an external temperature-compensated LC circuit.
3. Without external control voltage (pin 7 open), the IC automatically operates in mode 1.
4. Picture carrier PC = 38.9 MHz; sound carrier SC
5. Sound carrier SC = 32.4 MHz, modulated with f
